DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a side cross-sectional view of an embodiment 100 of atobacco smoking apparatus 10 that is configured for smoking cigarettetobacco. A cigarette loading port 180, also referred to as a tobaccoloading port 180, is shown in a closed position. As shown, an enclosure110, also referred to as a canister 110 or containment 110, includes anupper surface 112, a side surface 114 and a lower surface 116. Theenclosure 110 has a generally cylindrical shape. The upper surface 112and lower surface 116 are substantially circular and flat. The sidesurface 114 is substantially curved. In some embodiments, the uppersurface 114 and the lower surface 116 are dimensioned to have a diameterof approximately 4 inches, and the side surface 114 is dimensioned tohave a height (perpendicular to its curve) of approximately 4.75 inches.

The enclosure 110 includes an inhale/exhale port 130 that has anexterior portion that is also referred to as a nipple 130 and which isconfigured to attach to an inhale/exhale conduit 132. The inhale/exhaleconduit 132 includes a proximal end 134 having an attached mouthpiece138 and a distal end 136 which is configured to attach to and detachfrom the nipple portion of the inhale/exhale port 130 of the enclosure110. Preferably, the nipple 130 is made of aluminum, the inhale/exhaleconduit 132 is made of rubber and the mouthpiece 138 is made of nickel.

The enclosure 110 also includes an air input port 140 and a gas outputport 150. The air input port 140 is configured to input atmosphericgases, collectively referred to as air, that reside outside of theenclosure 110. The air input port 140 is configured to input air when adetected pressure of internal gases residing inside of the enclosure,also referred to as an internal gas pressure, is substantially less thana detected pressure of the air residing outside of the enclosure, alsoreferred to as atmospheric pressure. Preferably, the input port isimplemented as a pressure sensitive one way valve that actuates (opens)upon less than 0.5 pounds per square inch (PSI).

The gas output port 150 is configured to output the internal gasesresiding inside of the enclosure 110. The gas output port 150 isconfigured to output the internal gases, including smoke and otherparticulates, when the internal gas pressure of those internal gases issubstantially greater than the atmospheric pressure of the air residingoutside of the enclosure 110. The gas output port 150 resides with a gasoutput cavity 152 located at a bottom portion of the enclosure 110.Preferably, the gas output port 150 is implemented as a pressuresensitive one way valve that actuates (opens) upon a pressure differenceof less than 0.5 pounds per square inch.

An aluminum spacer (not shown) provides support from gravity to thefilters 122, 124 located above it and separates the gas output cavity152 from the remainder of the enclosure 110. Optionally, a layer ofwhite filter media is disposed between the charcoal filter 124 and thegas output cavity 152. The white filter paper is made from tightly wovencotton or cotton like material that functions as a dust barrier betweenthe granulated charcoal (charcoal dust) generated within the combustioncavity 174 and the gas output valve 150 disposed within the gas outputcavity 152.

In some embodiments, the portion of the enclosure 110 that surrounds thecombustion cavity 174 is made from stainless steel. In some embodiments,the height of the side surface 114 of the combustion cavity isapproximately 1.25 inches. Optionally, a remaining portion of theenclosure 110, not surrounding the combustion cavity 174, can be madefrom other types of material, such as an acrylic.

The enclosure 110 also includes a cigarette loading apparatus 160,including a cigarette loading port 180, that assists with the loading(transfer) of pre-combusted tobacco in the form of a cigarette, into theenclosure 110 and that assists with the output (transfer) ofpost-combusted tobacco from the enclosure 110. In this embodiment, thecigarette loading apparatus 160 is configured to assist the loading of apre-combusted cigarette from outside of the enclosure 110 to inside ofthe enclosure 110 via a sliding cigarette attaching device 162, alsoreferred to as a cigarette holder 162. Preferably, the cigarette holder162 is made from stainless steel.

The cigarette holder 162 is shaped like a cup without an attachedhandle. The cup has an open side (mouth) and an opposing passageway side(base). The open side provides access to a cavity that resides withinthe boundaries of the cup. The cavity is dimensioned to receive andengage (attach) to one end of a cigarette via a “snug fit” type ofengagement. A user of the device 10 can open the cigarette loading port180 and push a cigarette into the cigarette holder 162 and/or pull acigarette out of the cigarette holder 162 while applying a small amount(less than a pound) of force.

The passageway side (base) provides a passage 190 for combustionproducts to flow into a hollow rod 164 and towards the inhale/exhaleport 130. The rod, which is hollow, also has a breathing hole 192 (SeeFIG. 5A) along its top side so that the flow of tobacco combustionproducts can exit the rod 164 and exit the enclosure 110 via theinhale/exhale port 130. In other embodiments, not shown, the cigaretteholder 162 is formed by the end of a continuous tube that is dimensionedto accommodate a cigarette.

The cigarette loading apparatus 160 also includes a rod 164 having aproximal end 166 and a distal end 168. The rod 164 is configured toslide through a rod port 170. The distal end 168 of the rod 164 isconfigured to attach to the base of the cup of the cigarette holder 162and to reside within the enclosure 110. The proximal end 166 of the rod164 is configured to reside outside of the enclosure 110. Optionally,and as shown, the rod 164 includes a knob 172, also referred to as anend cap 172, having a knurled outer surface (not shown). The knob 172 isconfigured to enable a user of the device 10 to grasp and pull the rod164 substantially out of, or push the rod 164 substantially into, theenclosure 110.

The cigarette loading apparatus 160 also includes a cigarette loadingport 180 that resides at a location opposite to the rod port 170. Thecigarette loading port 180 is a circular shaped opening that isdimensioned to allow for the passage of a cigarette of standard size.The cigarette of standard size also referred to herein as a cigarette,has a forward end and a back end. The cigarette is configured so thattobacco combustion occurs at its forward end when the cigarette is lit(lighted) and configured for a person (user) to inhale substancesproduced from the tobacco combustion from the back end of the cigarette.

When the rod 164 is pushed substantially into the enclosure, the cupshaped cigarette holder 162 that is attached to the distal end 168 ofthe rod is positioned proximate to the cigarette loading port 180. As it162 is attached to the rod 164, the cup shaped cigarette holder 162 isoriented so that its opening (mouth) faces the cigarette loading port180.

The cigarette loading apparatus 160 resides within a tobacco combustioncavity 174 that occupies a top portion of the enclosure 110. The device10 is configured so that tobacco combustion occurs and tobaccocombustion products are produced within the tobacco combustion cavity174. A first portion of the tobacco combustion products are output fromthe enclosure 110 via the inhale/exhale port 130 and the gas output port150. A second portion of the tobacco combustion products are collectedby and contained within the enclosure 110 via the one or more filters122, 124. Preferably, the cigarette holder 162 and the rod 164 are madefrom stainless steel.

The upper surface 112 and the side surface 114 of the top portion of theenclosure 110 that surrounds the tobacco combustion cavity 174 ispreferably made of stainless steel. The side surface 114 below thatenclosing the combustion cavity 174 and the bottom surface 116 arepreferably made of acrylic material.

FIG. 2 illustrates a side cross-sectional view of an embodiment atobacco smoking apparatus 10 with the cigarette loading port 180 in anopen position. When the cigarette loading port 180 is in the openposition (See FIG. 2) and when the cigarette holder 162 is locatedproximate to the cigarette loading port 180, a user can push the backend of a cigarette through the cigarette loading port 180, through theopening of and into the cup shaped cigarette holder 162 in order for it162 to engage and attach to the back end of the cigarette.

In a typical use scenario, the user of the device 10 inserts the backend of a cigarette into the cigarette holder 162 as described above (SeeFIG. 3). In this circumstance, the back end of the cigarette is disposedinside of the enclosure 110 while a remaining portion of the cigarette,including its front end, is disposed substantially outside of, andprotrudes from, the enclosure 110.

FIG. 3 illustrates a side cross-sectional view of an embodiment of atobacco smoking apparatus with an unlit cigarette 202 being loadedthrough the cigarette loading port in an open position. Continuing theuse scenario described above, the user pulls the rod 164 substantiallyout of the enclosure to transfer the entire cigarette 202 into theenclosure (See FIG. 4). When the rod 164 is pulled substantially fromthe enclosure, the cup shaped cigarette holder 162 that is attached tothe distal end 168 of the rod is pulled sufficiently away from thecigarette loading port 180 so that the entire attached cigarette 202 ispulled into and entirely enclosed within the enclosure 110. In thisposition, the back end of the cigarette 202 is proximate to theinhale/exhale port 130 and the front end of the cigarette 202 isproximate to the cigarette loading port 180.

The user next lights (places in physical contact with a) the cigarette202 as it is preferably disposed within and proximate to the cigaretteloading port 180. Optionally, the cigarette 202 can be lit when it isprotruding from the cigarette loading port 180, before it is pulled intothe enclosure 110. The cigarette 202 is now lit (not shown).

Next, the air input port 140 is closed by pivoting the outside(pivotable) portion 140 b of the air input port 140 to the enclosuresealing position. When in the enclosure sealing position, the air inputport 140 is operable to respond to the pressure of the internal gaseswithin the enclosure 110.

FIG. 4 illustrates a side cross-sectional view of the embodiment of thetobacco smoking apparatus 10 with a lit cigarette 202 being fully loadedwithin the enclosure 110 and the cigarette loading port 180 being in aclosed position. Tobacco combustion occurring at the front end of thelit cigarette 202 produces combustion products 208 which fill thetobacco combustion cavity 174. As shown, the distal end 136 of theinhale/exhale conduit 132 is attached to and substantially surrounds thenipple of the inhale/exhale port 130.

Continuing the use scenario described above, the user (not shown) nextengages the mouthpiece 134 of the inhale/exhale conduit 132 via his/hermouth and inhales through the inhale/exhale conduit 132. Inhalingthrough the inhale/exhale conduit 132 causes a reduction in the internalgas pressure of the enclosure 110 and causes substances produced fromthe tobacco combustion to exit the back end of the cigarette 202 and theenclosure 110 and to travel through the inhale/exhale port 130 and theinhale/exhale conduit 132 to the user.

The reduction of internal gas pressure causes the air input port 140 toopen and to input air from the atmosphere into the enclosure 110. Theair that is input from the atmosphere mixes into forms a portion of theinternal gases residing within the enclosure 110.

Next, the user exhales through the inhale/exhale conduit 132. Exhalingthrough the inhale/exhale conduit 132 causes an increase to the internalgas pressure of the enclosure 110 and causes substances 208 producedfrom the tobacco combustion to cease traveling from the enclosure 110and through the inhale/exhale conduit 132 to the user. The increase ofinternal gas pressure within the enclosure 110 causes the gas outputport 150 to open and to allow the internal gases from the enclosure 110to output (discharge) from the enclosure 110.

The enclosure 110 is configured so that any flow of the internal gasesfrom the combustion cavity 174 to the gas output port 150 travelsthrough the one or more filters 122, 124. The enclosure 110 isconfigured so that there is no path within the enclosure 110 whereinternal gases from the combustion cavity 174 can flow to the gas outputport 150 without traveling through the one or more filters 122, 124.Hence, internal gases residing within the enclosure 110 travel throughthe one or more filters 122, 124 before being output through the gasoutput port 150 and into the atmosphere.

In this embodiment, the internal gases pass through the HEPA filter 122and the carbon filter 124. The HEPA filter 122 and the carbon filter 124are disposed in series along a longitudinal axis 118 of the enclosure110. A HEPA (high efficiency particulate arrestant) filter 122 isconfigured to filter small particles mixed with the internal gasses.Typically a HEPA filter can filter particles that are less than a micronin diameter. The carbon filter 124 is configured to reduce unpleasantodors and filter particles that are typically larger than thoseparticles that are filtered by a HEPA filter 122, from the internalgases.

The device 10 substantially filters and removes particles and unpleasantodors included within second hand smoke, produced from tobaccocombustion, before discharge into the atmosphere. This second hand smoke(particles and unpleasant odors) is believed to cause ill health effectsamong those people exposed to it. Also, this second hand smoke isgenerally considered a nuisance. As a result, people within proximity ofthe user (smoker) of the device 10 are substantially less affected bythe ill health affects and nuisance of second hand smoke.

FIG. 5A illustrates a view of the top surface 112 of the tobacco smokingapparatus 10 of FIGS. 1-4. As shown, the cigarette loading 180 port isin an open position. A first hinge piece 540 a is attached to the baseportion 140 a of the air input port 140. A second hinge piece 540 b isattached to the outside (pivotable) portion 140 b of the air input port140.

A cross-sectioned outline of the cigarette loading apparatus 160 that islocated below and obstructed from view by the top surface 112, is shownas being marked with dashed lines. As shown, the breather hole 192 islocated proximate to the inhale/exhale port 130.

As shown, outside (pivotable) portion 140 b of the air input port 140 ispivoted away from the base portion 140 a of the air input port 140 andis in an enclosure unsealing position. In this enclosure unsealingposition, the cigarette loading port 180 is exposed and available foruse. When the base portion 140 a and the outside (pivotable) portion 140b of the air input port 140 are closed together and abutting each other(Shown in FIGS. 1, 4 and 5B), the air input port 140 is in an enclosuresealing position. In the enclosure sealing position, the cigaretteloading port 180 is not accessible to the user and is not available foruse.

FIG. 5B illustrates a view of the bottom surface 116 of the tobaccosmoking apparatus 10 of FIGS. 1-4. As shown, the cigarette loading 180port is in a closed position. As shown, outside (pivotable) portion 140b of the air input port 140 is pivoted towards and abutting the baseportion 140 a of the air input port 140. In this enclosure sealingposition, the cigarette loading port 180 is not exposed (obscured) andnot available for use.

FIG. 6 illustrates a side cross-sectional view of an embodiment 600 of atobacco smoking apparatus 10 that is configured for smoking loosetobacco. This embodiment 600 of the invention enables a user to smokeloose tobacco like the loose tobacco that is smoked within a tobaccopipe.

This embodiment 600 is structured substantially like the cigarettesmoking embodiment 100 of FIGS. 1-5B with the exception that thecigarette loading apparatus 160 (including the cigarette loading port180) is eliminated from the enclosure 110 and that the air input port140 of the first embodiment 100 (See FIG. 1) is relocated from the sidesurface 114 to the top surface 112 of the enclosure 110.

As relocated onto the top surface 112, the air input port 640 of thisembodiment 600 (Now identified using reference number 640 instead of140) is structured and functions the same as the air input port 140located on the side surface 114 of the first cigarette smokingembodiment 100 (See FIG. 5A). Like the air input port 140, the air inputport 640 includes a base portion 640 a and the outside (pivotable)portion 640 b and is hinged in the same manner (not shown in FIG. 6) asdescribed in FIG. 5A. Unlike the air input port 140, the outside(pivotable) portion 640 b of air input port 640 pivots and opensupwards, instead of pivoting and opening sideways as shown for FIGS. 2and 5A.

Also like the cigarette input port 180 of the first embodiment 100,tobacco is entered into the enclosure 110 via a loose tobacco input port680, also referred to as a tobacco loading port 680. Instead oftransferring a cigarette into the enclosure 110, loose tobacco istransferred (dropped and/or pushed) into the tobacco input port 680.

Unlike the first cigarette smoking embodiment 100, a loose tobacco bowl690, constructed from a fine meshed metal screen, is disposed below thetobacco input port 680 and stores any loose tobacco transferred into theenclosure 110 via the loose tobacco input port 680. In a typical usescenario, the user lights the loose tobacco stored within the loosetobacco bowl 680, typically using a flame extending through the tobaccoinput port 680. The loose tobacco bowl 680 separates combusting(burning) loose tobacco that is stored within it 680 from any remainingportion of the tobacco combustion cavity 174 and the enclosure 110.

Combustion products that are sufficiently small to pass through the finemesh metal screen can enter any remaining portion of the combustioncavity 174 and exit the enclosure 110 via the inhale/exhale conduit 132or via the gas output value 150.

Preferably, various contact points and edges located between separatecomponents of the device 10 are sealed using a rubber material. Forexample, the circular perimeter of the air input valve 140, of the gasoutput valve 150, of the hollow rod 164, of the stainless steel topportion of the enclosure 110 and of the nipple 130 can be sealed using arubber “o ring” type of seal. Also, components can be threaded tomechanically attach to each other and washers can be used tointeroperate with the threaded portions of the threaded components,where appropriate.

FIG. 7 illustrates a side and a top cross-sectional view of anembodiment 700 of a flapper valve that is implemented a gas output port150. As shown, a flapper valve housing 710 is oriented so that internalgases from the enclosure 110 can flow through an inlet port 712 and makephysical contact with a flapper 716. The flapper 716 is bowed in theupwards direction and towards the inlet port 712 and towards theinternal gases residing within the enclosure 110. A center portion ofthe flapper is in physical contact with and physically held in place bya flapper support 718 in a position adjacent to the inlet port 712.

The flapper 716 is manufactured to have a flat and circular shape whenit is not being influenced by outside forces. Outside forces supplied bythe flapper support 718 and by an inner surface 724 of the housing 710force the flapper 716 to bow against its otherwise flat shape.Preferably, the flapper is manufactured from material, such as silicone,that permits its integrity to be maintained at temperatures of 400degrees Fahrenheit. In some embodiments, the flapper valve housing 710is made from aluminum. Preferably, a rubber o-ring is employed as a sealbetween the flapper valve housing 710 and the enclosure 110.

When a difference between an internal gas pressure of the internal gasesresiding inside of the enclosure 110 is less than or equal to anatmospheric pressure of said atmospheric gases residing outside of theenclosure 110, portions of the flapper 716 that are located outside ofthe center portion of the flapper 716 are configured to form a flatsurface and as a result, press upward (not shown) to make physicalcontact with an outer rim 713 of the inlet port 712 and the innersurface 724, to fully obstruct any flow of internal gases through theinlet port 712 and through the flapper valve 700.

When a difference between the internal gas pressure of internal gasesresiding inside of the enclosure 110 is sufficiently greater than theatmospheric pressure of said atmospheric gases residing outside of theenclosure 110, portions of the flapper 716 that are located outside ofthe center portion of the flapper 716 that are in physical contact withthe flapper support 718, are pushed by the internal gases in a directiontowards and against the flapper support 718. As a result, a gap 720 isformed between the outer rim 713 of the inlet port 712 and the flapper716. The gap 720 eliminates the full obstruction of the flow of internalgases through the inlet port 712, and enables the flow of internal gasesaround a gap 722 adjacent the outer edge of the flapper 716 and outthrough the one or more outlet ports 714 of the flapper 716.

In some embodiments, the difference is sufficiently greater by 0.25pounds per square inch or less. In some embodiments, the difference issufficiently greater by approximately 0.1 pounds per square inch.Optionally, grooves can be etched along the inner surface 724 of thehousing 710 to enhance the flow of internal gases around the flapper716.

This embodiment 700 of a flapper valve can also be implemented as an airinput valve 140 where the direction of the flow of gas, being air, isdirected into instead of out of the enclosure 110. Various knownembodiments of a flapper type of valve, or other types of pressuresensitive one way valves, can be manufactured or purchased off the shelfand employed to implement the air input port 140 and/or the gas outputport 150 valves.

While the present invention has been particularly shown and describedwith reference to the preferred mode as illustrated in the drawing, itwill be understood by one skilled in the art that various changes indetail may be effected therein without departing from the spirit andscope of the invention as defined by the claims.
